PAUL BABCOOK, JR, OF MONTOLAIR, NE\V JERSEY.

' LAMP.

SPECIFICATION forming part of Letters Patent No. 310,635, dated January13, 1885;

Application filed December 20, 1883. (No model.)

To all whom, it may concern:

Be it known that I, PAUL BABCOOK, Jr., of Montclair, in the county of-Essex and State of New Jersey, have invented a new and usefulImprovement in Lamps, of which the following is a specification.

My invention relates more particularly to lamps for burning kerosene orother products of petroleum, although it may be applicable to lamps forburning other oils.

The object of my invention is to provide a simple and inexpensiveattachment which may be readily applied to the wick of alamp,

and by which the wick will be inclosed from a point above the oil orburning-fluid to a point near the bottom of the lamp, the wick beingthereby compelled to take its supply of oil or fluid from the lower andheavier stratum of oil in the lamp-reservoir, in order to consume theheavier portion of oil while there is a considerable head of lighter oilabove, leaving the lighter oil to be consumed when the capillary powerof the wick is least.

The invention consists in an attachment for a lamp-wick made independentof the burner, and consisting of a tube or tubular guard or shield openat the ends, and adapted to receive the wick through it or to be slippedupon the wick, and provided with inward projections which will hold onthe wick sufficiently strongly to prevent the tube or shield fromslipping down thereon when in use in a lamp.

The invention also consists in the combination, with a lamp, of a tubeor tubular shield of the kind above described, fitted to or receivingthrough it the lamp-wick, and adapted to abut against the under side ofthe burner, and to be there held against upward movement while the wickis moved upward by the feeding mechanism, all as more fully hereinafterdescribed.

In the accompanying drawings, Figure 1 represents a sectional elevationof a lamp having my improved attachment applied to its wick; and Fig. 2is a sectional view of a piece of wick and my attachment in a plane atright angles to the plane of Fig. 1.

Similar letters of reference designate corresponding parts in bothfigures.

. A is the fount or reservoir, and B a burner applied thereto in theusual way.

0 designates the wick, and O the ordinary wick-tube of the burner.

D designates the tube or tubular shield or guard, which surrounds thewick G from a point near the bottom of the burner B to a point near thebottom of the fount or reservoir A. The tube or guard D extends entirelybelow the ordinary level of oil when the lamp is full, and compels thewick C to draw its supply from the lower portion or stratum of thevolume of oil in the fount or reservoir A; hence the heavier oil at thebottom of the fount or reservoir will be consumed while there is aconsiderable head of oil above it, and the lighter oil will be consumedwhen the capillary power is least. The shield or guard D is suspendedfrom the wick itself, and constitutes an attachment to the wick entirelyseparate from and independent of the burner. This attachment may bepurchased at small cost and applied by any unskilled person to the wick.It is open at both ends, and should fit the wick loosely enough so asnot to prevent the free upward flow of oil through the wick.

In order to hold the shield or guard against slipping down on the wick,I provide it with inwardly projecting or deflected portions, which bearon the wick. I have here shown the shield or guard havinginwardly-turned spurs or prongs s, which have a hold on the wick. \Vhenthe wick is fed upward by the usual feed-ratchet, of which a is thespindle, the upper end of the shield or tube D is stopped by strikingagainst the under side of the burner, and the wick is drawn up throughsaid shield or guard.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is

1. The attachment for a lamp-wick herein described, consisting of atubular and openended shield or guard made independent of anylamp-burner, adapted to receive the Wick through it, and of a length toextend from a point near the bottom of a reservoir considerably abovethe .level of fluid therein, the said shield or guard being providedwith inwardly-deflected portions adapted to bear upon the wick andprevent the shield or guard from slipping downward thereon,substantially as and for the purpose herein described.

2. The tubular shield or guard D for ala1np- Wick, open at both ends,and provided with .independentlyoftheburner, andhavingaslip- 1oinwardly-presented spurs or prongs s, substanconnection With the Wickwhich enables the tially as and for the purpose herein described.
